Gig Summary
Vetted by Fiverr Pro
Loopus Tech was selected by the Fiverr Pro team for their expertise.
About this gig
You built 80% of your app with Lovable, Bolt or Base44?
I finish the last 20% that AI can't.
The demo looks great, but the auth doesn't really work, Stripe isn't connected, half the buttons do nothing, and you have no idea how to put it online. That last stretch is exactly what I do.
How it works, 100% async:
Send your app link and tell me what's missing. I start within 24h on weekdays and deliver working, deployed results. Everything happens through Fiverr chat, no calls needed.
What I finish: unfinished screens and features, authentication, Stripe payments, OpenAI and API integrations, Supabase database and security, production deployment on Vercel, Netlify or Railway.
Why founders trust me with their app:
Fiverr Pro vetted. 15+ years of senior engineering. 300+ orders, 4.9 rating on my profile. Clean code, not more AI prompts: every change is committed step by step and rollback safe. Free NDA on request. English and French.
Not sure what's missing in your app? Message me with the link. I'll tell you for free which package covers it. Average response: 1 hour, weekdays CET.

FAQ
I built my app with Lovable / Bolt / Base44 but I'm not technical. Can you still help me?
Yes, that's exactly who I work with. You don't need to understand the code. Just send me your app link (or invite me to your Lovable/Bolt project), describe what's broken or what you need finished, and I'll handle the technical side. I'll explain decisions in plain English along the way.
What if you break something while fixing my app?
Every change I make is committed step by step, so we can always roll back. For Standard and Premium packages, I work on a separate branch or copy, test thoroughly, and only push to production once you approve. Your working features stay working.
Do you sign an NDA? Is my code/idea safe?
Absolutely. I can sign an NDA before we start at no extra cost. I've been on Fiverr since 2016 with 270+ orders and zero confidentiality issues. Your code, credentials, and product idea stay strictly between us.
How do I know which package to pick?
Send me your app and a short description of what's blocking you. I'll review it for free and recommend the right package (or a custom offer if needed). Don't worry about picking the wrong one — we adjust together before you order.
What if my issue is bigger than the package I bought?
No problem. If we discover the scope is larger once I dig in, I'll send you a clear custom offer with the difference. You're never locked in or surprised. Many clients start with Basic as a diagnosis and upgrade once we have a plan.
Can you add new features, not just fix bugs?
Yes. The Premium package includes up to 5 features, 2 API integrations, Stripe/admin work, QA and deploy. For larger feature builds, I send a custom offer or we switch to the hourly plan.
Which stacks and tools do you work with?
Lovable, Bolt, Base44, v0, Cursor on the AI side. Supabase, Firebase, PostgreSQL for data. Stripe, OpenAI, Resend, Twilio for integrations. Vercel, Netlify, Railway, AWS for deploy. Next.js, React, Node, TypeScript for clean code rewrites when needed.
How fast can you start? And how do we communicate?
I'm online most weekdays (CET) with a 1-hour average response time. I usually start within 24 hours of order. We communicate via Fiverr chat, with optional shared Notion/doc for larger projects.
Do you offer revisions and post-delivery support?
Yes. Basic includes 1 revision, Standard 2, Premium unlimited within scope. Premium also includes 30 days of post-launch support for any bug related to the work delivered. I don't disappear after delivery.
Why is your gig more expensive than other Fiverr developers?
Because I'm not a prompt-fixer. I'm a Fiverr Pro–vetted senior developer with 15+ years of experience, working on production-grade code that scales. Cheaper gigs often patch symptoms with more AI prompts, which compounds the technical debt. My fixes are clean, documented, and built to last — so you
